Senior Research Scientist - Analytical LC/MS Characterization

Full MS spectra followed by MS/MS or All Ions acquisition enables applications in pharmaceutical and life science industry, as well as government agencies. Agilent LC-MS QTOF. II. Scope and Implementation: This SOP applies to Agilent LC-MS QTOF instrument located in the Life Sciences Research Building, room LS1151. III. Introduction: The Agilent 6530B Accurate Mass Quadruple Time-of-Flight mass spectrometer is equipped with dual electrospray ionization source and an Agilent 1260 UPLC liquid Analytical characteristics of the LC-QTOF/MS method The UHPLC coupled QTOF/MS method was abletoseparate and identify 74 analytes. The 2- and 3-hydroxyadipic acid isomers could not be resolved due to identical retention times and were therefore analyzed as one combined signal. Adipic acid and 3-methylglutaric acid have the same mass and com- 2019-03-30 · LC-MS/QTOF identification of phytochemicals and the effects of solvents on phenolic constituents and antioxidant activity of baobab (Adansonia digitata) fruit pulp 1.

2.2. Instrumentation and analytical conditions for the LC-QTOF-MS 2.2.1. Agilent 1290 HPLC Qualitative tandem liquid chromatography quadrupole time of flight mass spectrometry (LC-QTOF-MS/MS) was utilized to identify compounds in the extract. The data processing revealed the presence of 76 known compounds in the crude extract from the leaves. LC-QTOF/MS had significantly improved recovery for: pyroglutamic acid, tiglylglycine, and 3- hydroxyisobutyric acid. For oxoglutaric acid and meva- lonic acid, the LC-QTOF/MS recovery was below 80% butstillsatisfactoryfordiagnosticpurposes.BothGC-MS (medians of all labs) and LC-QTOF/MS methods had The LC-ESI-QTOF/MS analysis led to the identification of 138 phenolic compounds in three black spices.

HPLC separations Efficient strategies are required to implement comprehensive suspect screening methods using high-resolution mass spectrometry within environmental monitoring campaigns. In this study, both liquid and gas chromatography time-of-flight mass spectrometry (LC-QTOF-MS and GC-QTOF-MS) were used to screen for >5000 target and suspect compounds in the Sacramento–San Joaquin River Delta in Northern We got a good offer from Shiumadzu LC-MS 9030 QTOF and I would like to know, if we can do quantitative proteomics study and small molecule analysis with this QTOF.

It is ideally suited for proteomics applications. Peak Scientific Instruments Genius XE SMZ. Peak introduced the Genius XE SMZ, a nitrogen and air generator for Shimadzu LC–MS and other systems.

LC-MS and LC-MS/MS are the combination of liquid chromatography (LC) with mass spectrometry (MS). MS means you only analyze your precursor ion (as generated in the source) for example in an The Agilent QTOF 6540 is equipped with exchangeable ESI/APCI ion sources.
